Py to exe pyinstaller import errors

Im trying to convert a single file python script/project into an exe using pyinstaller
Even thought pyinstaller converts the script the .exe will run and throw this
Traceback (most recent call last):
File "main.py", line 4, in <module>
File "PyInstaller\loader\pyimod03_importers.py", line 540, in exec_module
File "pynput\__init__.py", line 40, in <module>
File "PyInstaller\loader\pyimod03_importers.py", line 540, in exec_module
File "pynput\keyboard\__init__.py", line 31, in <module>
File "pynput\_util\__init__.py", line 76, in backend
ImportError
[16676] Failed to execute script main
I'm stumped , through my trial and erroring i figured that when i replace pynput with a module like random the convertion works fine , but i need it to work with pynput
please help , thanks in advance!

Authors made some changes which i feel broke the reference.
so instead of package it is referring file.
- backend = backend(__package__)
+ backend = backend(__name__)
pls try to downgrade your package and check that your app still works.
pip install pynput==1.6.8
then your command like following would work.
pyinstaller --onefile build_pkg_for.py

Py2exe NotImplementedError: resource_filename() only supported for .egg, not .zip

I am trying to convert a python file into an executable and for that I'm using py2exe. When running the setup.py script to generate the dist folder and the executable file everything goes well.
What goes wrong is that when I'm running the executable the following error message gets displayed:
Traceback (most recent call last):
File "q400.py", line 16, in <module>
File "SUAVE\__init__.pyc", line 12, in <module>
File "SUAVE\Plugins\__init__.pyc", line 11, in <module>
File "SUAVE\Plugins\load_plugin.pyc", line 37, in load_plugin
File "SUAVE\Plugins\pint\__init__.pyc", line 23, in <module>
File "SUAVE\Plugins\pint\unit.pyc", line 423, in __init__
File "pkg_resources\__init__.pyc", line 1171, in resource_filename
File "pkg_resources\__init__.pyc", line 1872, in get_resource_filename
NotImplementedError: resource_filename() only supported for .egg, not .zip
When I check the file unit.pyc at line 423 the code is:
data = pkg_resources.resource_filename(__name__, 'default_en.txt')
And when I check the library.zip in the dist folder there is no default_en.txt file, however, it is present in the site-packages module.
So is it because this file is a txt file that this error shows up?
I tried to force py2exe to import it but with no success.
Also I found a similar question here but the answer can't be applied in my case because I don't have any egg nor zip files implicated in the error (at least in my opinion).
Thank you

PyInstaller "You may load I/O plugins with the `skimage.io.use_plugin`"

useing Pyinstaller packages a python script
Pyinstaller version 3.2

File "<string>", line 57, in <module>

You may load I/O plugins with the `skimage.io.use_plugin` command. A list of all available plugins can be found using `skimage.io.plugins()`.
file_test returned -1
I have been getting above error. Could some one please tell me how would i fix it?

The problem seems to be related to this github issue, essentially the skimage.io._plugins submodule is making life hard for Pyinstaller.
To make sure everything you need is packaged you should have a hook file that contains
from PyInstaller.utils.hooks import collect_data_files, collect_submodules
datas = collect_data_files("skimage.io._plugins")
hiddenimports = collect_submodules('skimage.io._plugins')
(or if you already have a hook file with these, extend the current datas and hiddenimports).

building matplotlib with pyinstaller 2.0

I am trying to use pyinstaller 2.0 to build an .exe file from a python script which uses matplotlib and numpy, but I keep failing. I tried this code from
Building python pylab/matplotlib exe using pyinstaller
as a simple reference, I get the build done for me, but when I run the exe I get the error:
Traceback (most recent call last):
File "<string>", line 12, in <module>
File "C:\Compilations\pyinstaller-2.0\PyInstaller\loader\iu.py", line 386, in
importHook
mod = _self_doimport(nm, ctx, fqname)
File "C:\Compilations\pyinstaller-2.0\PyInstaller\loader\iu.py", line 480, in
doimport
exec co in mod.__dict__
File "C:\Compilations\pyinstaller-2.0\ptest\build\pyi.win32\ptest\out00-PYZ.py
z\PIL.PpmImagePlugin", line 27, in <module>
LookupError: no codec search functions registered: can't find encoding
Is this a bug or do I need to tinker with the .spec file and link the matplotlib libraries to pyinstaller somehow? If so - can anyone show me a simple example, please?
I tried cx_Freeze before and also seem to have a problem as soon as I use a code with matplotlib.
Thanks in advance!

Edit PpmImagePlugin.py and add 'import encodings' (without the quotes) before any other imports. I had the same problem and this fixed it. Source: http://www.pyinstaller.org/ticket/651

pyinstaller and win32com

So I'm confused about how to get pyinstaller to build an application that uses win32com. I have a script that runs with no problem from IDLE or command line that interacts with excel via
xl = Dispatch('Excel.Application')
followed by some other really basic excel calls, then closes. I've seen advice to include "clsctx=pythoncom.CLSCTX_LOCAL_SERVER" as an argument to Dispatch, but it doesn't change anything. Whenever I build the script, I get an error similar to this
Traceback (most recent call last):

That's copied from this german question http://www.python-forum.de/viewtopic.php?f=1&t=25010 but my error is basically the same. I tried to implement the advice given on that page to no avail either.
I know next to nothing about COM stuff, just hoping to get this little excel app to run.
EDIT: Also tried importing pythoncom and running "CoInitialize()" (based on this guy Call MS Access module function from Python after compiling with py2exe fails saying that his script ran fine with pyinstaller) but that didn't change anything either. Really at a loss here and appreciate any advice.

I'm not sure if you are still using py2exe, i was about to try your workaround when i stumbled into this thread:
Call MS Access module function from Python after compiling with py2exe fails
The "solution" was using Pyinstaller that has a bunch of workarounds implemented on by default depending on your script. I tried it with my pywin32 script that uses excel and word com objects and it worked perfectly without any tweaks.
